Answer: (D) 0.025 mol
Explanation:
The given balanced equation is :
According to stoichiometry :
4 moles of ammonia reacts with = 5 moles of oxygen
Thus 0.30 moles of ammonia reacts with =
moles of oxygen
Now as given moles of oxygen are more than the required amount, oxygen is the excess reagent.
moles of oxygen left = 0.40 - 0.375 = 0.025
Thus 0.025 mol excess reagent remains.
